Gardasil and Cervarix are similar drugs promoted as a cervical cancer vaccine.
The drugs vary in the types of
human papillomavirus (HPV) they treat, which is the virus said to cause
cervical cancer.
Gardasil, manufactured by
Merck, Inc., is promoted as the only
cervical cancer vaccine that helps protect against four kinds of
HPV (types 6, 11, 16 and 18), including two types that cause 70 percent of
cervical cancer cases, and two more types that cuase 90 percent of
genital warts cases.
Cervarix, manufactured by
GlaxoSmithKline, is not currently available in the
United States, but was approved for use in the U.S. by the FDA on October 16, 2009, and is expected to enter the market here by late 2009. It is already approved for use in Australia, the Phillipines and the
European Union. It is used in the UK for a national program of vaccination for teen and pre-teen girls to target two types of
HPV (types 16 and 18) for the prevention of
cervical cancer and pre-cancers.
Both
Gardasil and Ceravix are marketed to be given to girls and young women as young as age 9, and up to age 26.
Since
Gardasil’s introduction in 2006, the
Vaccine Adverse Event Reporting System (VAERS) has received more than 15,000 reports of adverse side effects related to
Gardasil. These reports include
serious adverse
side effects including Guilliane Barre, lupus, seizures, paralysis, blood clots, brain inflammation and many others. There also have been 44 reported
deaths as a result of
Gardasil uses.
Cervarix has been linked to more than 2,000 cases of
serious, adverse reactions since the UK government began administering it to schoolgirls last year. One of the worst cases involved 14-year-old Natalie Morton, who collapsed and died in school in England just one hour after receiving the vaccine.
Then, on October 25, 2009, Dr. Diane Harper, lead researcher in the development of two human papilloma virus (
HPV) vaccines and director of the Gynecologic Cancer Prevention Research Group at the University of Missouri, told an audience of medical professionals that
Gardasil is largely unnecessary, and that it has
never been fully tested on females under the age of 15. This, despite strong marketing efforts to make the drug mandatory for girls, and product literature and advertising that state the product can be used by girls as young as age 9.
On Oct. 16, 2009, the same day GlaxoSmithKline got approval to market its Cervarix drug in the U.S. the FDA also granted approval to
Merck to
expand the use of Gardasil in the U.S. to treat
boys and men ages 9-26 for the prevention of genital warts.
Ad in the United States, and is recommended for girls and women ages 9-26 by manufacturer
Merck, Inc.
In February 2009, the
National Vaccine Information Center, a private vaccine-safety group, conducted a comparative study of adverse events reported following a Menactra (meningococcal) vaccine versus the
Gardasil vaccine. Both vaccines are recommended for youngsters in the same age group, at 11-12 years old (Menactra for boys and girls,
Gardasil for girls only). The study compares
VAERS data reported for each vaccine.
The study found that
Gardasil is associated with at least twice as many Emergency Room visit reports, four times more
death reports, five times more “did not recover” reports, and seven times more “disabled” reports, as compared to Menactra.
Other findings of this study show that compared to Menactra:
- Gardasil is associated with all reports of blood clots
- Gardasil is associated with at lest four times as many cardiac arrest reports
- Gardasil is associated with at least six times as many fainting reports
- Gardasil is associated with at least four times as many Lupus reports
- Gardasil is associated with at least 15 times as many stroke reports
